I installed on the SD card with no problem. However, when I booted the EV3 with the card it went through the whole setup and then stopped at "Start menu...". I shut it down and then restarted. Again got as far as "Start menu..." and then stopped.

krchilders are you sure you have copied the Java JRE to the SD card and that it is the correct version? It needs to be Java 7 not Java 8? If you are sure please try the setup again and make sure you have deleted all of the files from the DOS partition before you start.

If the system hangs at start menu, then there is a good chance that there is a problem with the Java install. If you can open up a shell (via telnet/ssh) to your EV3, login and try running java to see what happens. If you can't do that try the older jre.

Thank you so much for your reply.If the problem occurred after the boot, I will be able to access to EV3 via telnet/ssh.However it occurred on during the installation of the leJOS.Thus I couldn't configure the WiFi access point nor WEP password on it.It is impossible for me to use the telnet/ssh and can't confirm the problem now.

Instead of u55, I'm using previous version of JRE and worked fine with 0.8.1-beta.ejre-7u51-fcs-b13-linux-arm-sflt-headless-18_dec_2013.tar.gz

It seems the problem presists. Following suggestions in all previous posts didn't get me beyond "Starging menu". Reformatted and installed multiple times. Each time installs OK, reboots, starts EV3 and then freezes at "Starting menu". Tried with 51, 55 and latest Java versions. Any more suggestions?
